FIX validate partially correct AEAT response lines

[braito4]

Summary

A global ParcialmenteCorrecto response can contain rejected (Incorrecto) records. The module previously treated every partial response as successful and could persist a rejected invoice or cancellation as sent.

This change:

• accepts Correcto global responses
• accepts a partial response only when every line is Correcto or AceptadoConErrores
• rejects partial responses containing an Incorrecto, missing, or unknown line status
• applies the same rule to invoice and cancellation responses

Validation

• added seven focused response-status cases
• tests pass on PHP 8.3, 8.4 and 8.5
• PHP syntax and git diff --check pass
